Neither my car nor the donor had headlight washer. Which explains why this light was not operative.

About the CAT temp sensor: The resistance I got here was not working as it produced erratic resistance everytime I checked. So I visited the electronics market and without much effort got hold of a variable resistance (0 to 100 ohms). It works perfect once set to produce 15 ohms resistance. Before I connect it to ECM, can you confirm whether all I need to do is to connect the wires (red & white) to two interfaces of the variable resistance? Is there any thing else I need to pay attention to?

I believe if the light goes out, it means success.

yup. Just connect the two wires to the load.

As it's a variable resistance you could do a sweep and let us know whats the minimum it goes out at

Hi Rich,

Issue fixed. I connected the wires to the resistance and light goes out. Thankyou for the help mate! (Y)

The variable resistance I have ranges from 1.3 to 108 ohms. I checked all through the range, but the CAT temp light stays off until it is disconnected.

Thank you again for the guidance!

Regards,

Ali
